[jira] [Commented] (KAFKA-6802) Improve logging when topics aren't known and assignments skipped

["ASF GitHub Bot (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-6802?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16443022#comment-16443022 ] 

ASF GitHub Bot commented on KAFKA-6802:
---------------------------------------

bbejeck opened a new pull request #4891: KAFKA-6802: Improved logging for missing topics during task assignment
URL: https://github.com/apache/kafka/pull/4891
 
 
   If users don't create all topics before starting a streams application, they could get unexpected results.  For example, sharing a state store between sub-topologies where one input topic is not created ahead time results in log message that that "Partition X is not assigned to any tasks" does not give any clues as to how this could have occurred.
   
   Also, this PR changes the log level from `INFO` to `WARN` when metadata does not have partitions for a given topic.
